摘要
An efficient channel estimation method called time-domain weighted average(TWA) algorithm is proposed for coherent optical orthogonal frequency division multiplexing(CO-OFDM) systems. On the premise of calculating the associated weight of channel transfer function, a more exact channel characteristic is obtained by calculating the weighted average of the pilot transfer function in this algorithm. Compared with time-domain average(TA) algorithm, the TWA algorithm can reach the same bit error rate(BER) with fewer pilots, and it improves the performance of CO-OFDM systems.
